Rapid industrial growth resulted in the need to keep pace with generating capacity and to expand and strengthen the existing transmission & distribution systems. The SBU has about three decades of turnkey experience in both domestic and overseas projects and has so far successfully commissioned more than 10000 km of Transmission lines upto 400kV and 87 Substations upto 400kV. The SBU has considerable expertise of working in very tough hilly terrains and snowy areas.
The SBU has an in-house capability for designing Transmission Line Towers & Switchyard Structures and uses the latest version of I-TOWERS software for the same. For execution of survey work, Total Stations and Digital Theodolites and for Tower spotting, software like PLS CADD are used. The SBU has recently developed a drum scheduling software with which wastage of conductors is considerably reduced. The SBU uses an innovative Central Pillar Mechanism (Patent pending), which is an in house development for erection of Towers. This mechanism has improved the safe working system in addition to improving productivity and reduction in time and paved the way for faster execution. In addition the SBU uses motorized spacer cycles, working platforms and hydraulic compressors in stringing; self loading mixtures for concreting has brought drastic improvements in the construction methodology. Also the SBU has set the trend in the industry by introducing 'Vertical fall arrestors' and 'safety nets' in addition to various other Personal Protective Equipments.
The SBU is also executing an overseas project consisting of design, supply and construction of five 132kV / 66kV / 11kV primary electrical high voltage GIS substations based at Pearl Island, Qatar. The contract value is Rs. 340 crore ($ 76 Millions) approximately. |
